What is necessary for charging an Extreme DUI?

Charging an Extreme DUI typically requires corroborating evidence of impairment because the offense involves a higher level of concern regarding a driver's ability to operate a vehicle safely. This can include observable signs of drunkenness, such as impaired motor skills, poor coordination, erratic driving behavior, or other indications that suggest the driver is unfit to be on the road. Such evidence supports the claims made in court and is essential to prove the extent of impairment related to the driver's blood alcohol content (BAC).

While achieving a specific BAC above a certain threshold—often 0.15 or higher—is a crucial factor in defining an Extreme DUI, corroborative evidence provides a more comprehensive view of the driver's state at the time of arrest. It reinforces the rationale behind the charges by demonstrating how alcohol influenced the driver's behavior, not solely relying on BAC readings. This is especially important in jurisdictions that emphasize the overall impact of alcohol on driving abilities, beyond just numeric measurements of blood alcohol content.
